refactor: Remove jQuery dependency and consolidate JavaScript assets

- Rename vendor JS file to activeadmin/quill_editor.js to avoid conflicts
- Update import alias to use 'activeadmin/quill_editor' for consistency
- Remove jQuery-dependent legacy file (quill_editor_input.js)
- Simplify engine asset configuration - only one JS file now
- Update documentation with correct paths and import names
- All functionality preserved with vanilla JavaScript

BREAKING CHANGE: Drops support for jQuery-based initialization.
Applications using the legacy jQuery initialization will need to
update to the new module-based approach.

-# Session Summary - ActiveAdmin Quill Editor Modernization
-
-## Context
-We analyzed replacing Trumbowyg with Quill for ActiveAdmin 4.x and Rails 8 compatibility. After evaluating SunEditor (too large at 450KB after removing source maps) and Quill.js (~200KB), we chose to modernize the existing `activeadmin_quill_editor` gem.
-
-## Important Discoveries
-1. **Existing Test App**: The gem already has a full Rails test application at `spec/dummy/` (not using Combustion)
-2. **Existing Tests**: Comprehensive system tests already exist in `spec/system/`
-3. **Existing Formtastic Input**: `QuillEditorInput` class already exists, just needs jQuery removal
-
-## Key Decisions Made
-
-1. **Use Quill.js** instead of SunEditor
-   - Quill: ~200KB minified
-   - Clean delta-based architecture
-   - No jQuery dependency for the core library
-   - Existing gem foundation to build upon
-
-2. **Serve assets directly from vendor/assets**
-   - No NPM package needed initially
-   - Propshaft automatically serves from vendor/assets and app/assets
-   - Simple drop-in integration
-
-3. **Follow activeadmin_trumbowyg patterns**
-   - Combustion-based test app
-   - Modern CI with matrix testing (Ruby 3.3/3.4, Rails 7.x/8.x)
-   - Comprehensive GitHub Actions setup with caching
-   - ESBuild for test app assets
-
-## Files Created
-- `/data/activeadmin-quill_editor/docs/activeadmin-4-propshaft-update.md` - Complete migration guide
-- `/data/activeadmin-quill_editor/docs/session-summary.md` - This summary
-
-## Next Steps
-
-### Immediate Tasks
-1. Download Quill 2.x assets and place in vendor/assets
-2. Create new JavaScript initializer without jQuery
-3. Update Formtastic input class (already exists, just needs updates)
-4. Update existing spec/dummy test app for Propshaft/Rails 8
-5. Configure GitHub Actions CI/CD
-
-### Implementation Order
-1. **Asset Setup** (vendor/assets structure)
-2. **JavaScript Modernization** (remove jQuery)
-3. **Test App Updates** (spec/dummy with Propshaft)
-4. **CI/CD Setup** (GitHub Actions with matrix)
-5. **Documentation Update** (README, examples)
-
-### Testing Strategy
-- Use existing spec/dummy Rails app (no Combustion needed)
-- Update existing system tests, add missing cases from trumbowyg
-- Matrix test against Ruby 3.3/3.4
-- Test Rails 7.x and 8.x with ActiveAdmin 4.x beta
-- Consider adding Playwright for modern browser tests
-- SimpleCov for coverage with SonarQube integration
-
-## Technical Notes
-
-### Propshaft Asset Serving
-- Gems can provide assets in `vendor/assets` and `app/assets`
-- Propshaft automatically includes these paths in load path
-- No compilation needed for vendored assets
-- Digest stamping handled automatically
-
-### JavaScript API Changes
-Replace jQuery-based initialization:
-```javascript
-// Old (jQuery)
-$(document).ready(initQuillEditors);
-
-// New (Vanilla)
-document.addEventListener('DOMContentLoaded', initQuillEditors);
-document.addEventListener('turbo:load', initQuillEditors);
-```
-
-### Form Input Usage
-```ruby
-f.input :content, as: :quill_editor, input_html: {
-  data: {
-    options: {
-      theme: 'snow',
-      modules: { toolbar: [...] }
-    }
-  }
-}
-```
